clip.infline {spatstat} | R Documentation |
Take the intersection between a set of infinite straight lines and a window, yielding a set of line segments.
clip.infline(L, win)
L |
Object of class "infline" specifying a set of infinite
straight lines in the plane.
|
win |
Window (object of class "owin" ).
|
This function computes the intersection between
a set of infinite straight lines in the plane
(stored in an object L
of class "infline"
created by the
function infline
) and a window win
.
The result is a pattern of line segments.
A line segment pattern (object of class "psp"
).

To divide a window into pieces using infinite lines,
use chop.tess
.
L <- infline(p=1:3, theta=pi/4) W <- square(4) clip.infline(L, W)
